What are the 4 goals of wound care?

1. Minimize the consequences (prevent loss of life/limb)

2. Optimize wound healing (prevent infection, cost efficiency)

3. Minimize scar formation

4. Restore function

2

What is a good history question to ask when a horse comes in with a wound/laceration?

Is the animal current on tetanus vaccines?

3

What 3 things should be done when examining a wound?

1. Restraint, sedation

2. Wear gloves

3. Control hemorrhage by compression

4

What things should be assessed in a wound?

1. Tissue trauma

2. vascular supply

3. Involvement of other structures (synovial, nerve, tendon/ligament)

5

Equines often come in with very _____ wounds.

contaminated

6

Equines have a ____ inflammatory response. What are consequences of this?

less intense/efficient;

May predispose to infection; soil decreases WBC effectiveness

7

Ponies heal _____ than horses.

faster

8

What part of the equine body has delayed healing?

Wounds on limbs (distal)

9

What is proud flesh?

Exuberant granulation tissue

10

What might you need to do prior to lavage or treatment of a wound?

block (lidocaine, mepivicaine), sedate

11

How do you properly use a local nerve block?

SQ, stay away from laceration edges, upside down "V" or "U"

12

What are 3 types of debridement that can be used?

1. Sharp

2. Mechanical

3. Biological

13

What can be used for sharp debridement?

scalpel, scissors

14

What can be used for mechanical debridement?

Lavage 10-15 psi, wet to dry bandages

15

19 ga needle on 35 ml syringe

16

What can we use for biological debridement?

Fly larvae (maggots) sterile, medical grade

25

Delayed primary closure is done before the appearance of _____.

granulation tissue

26

What are the initial steps in delayed primary closure?

27

How long after wound occurrence would you do secondary closure?

>5 days

28

Secondary wound closure is done after apprearance of _____.

granulation tissue

29

What type of wounds are involved in secondary closure?

contaminated or dirty wounds

30

What do you want to do with granulation tissue and skin edges prior to secondary closure?

debride it
